Mercedes Benz is generally considered to be of higher quality, but we have experienced problems with our 2009 C Class that we never experienced with any other car. The sunroof glass fatigued and imploded into the car while driving on the highway, ignition problems prohibiting the car from starting, electrical gremlins that causes the passenger side front and rear lights to turn on randomly while parked which of course kills the battery. While it is a technologically advanced car as deemed by M-B they do not acknowledge any responsibility for these problems. M-B dealers treat you like royalty when you purchase a car but then treat you like a parasite when reporting such problems. My advice is to get rid of your Benz when the warranty expires to save yourself some VERY expensive unexpected repairs.
